An approach to PVCI-based wrapper design

The methodology of IP reuse can improve the productivity of SoC development dramatically. But interfacing IPs which may have different pin structures, data widths or communication protocols is a tedious task. Designing a standard wrapper for each IP is a popular solution. Different from other interface synthesis approaches, this paper proposes a new approach to designing a PVCI-based wrapper. The proposed algorithm offers a base state machine platform on which designers can produce a FSM for a wrapper. This method has been employed to generate several real-purpose wrappers for IPs including VMI.
